Abstract: 1,238,598. Electron guns. GENERAL ELECTRIC CO. Ltd. 11 May, 1970 [17 June, 1969], No. 30652/69. Heading H1D. A cold cathode electron gun for an electron beam welding or cutting apparatus comprises an anode structure including an aperture which is movable with respect to the cathode in order to vary the electron path. In Fig. 1 the anode 8 comprises two short tubular parts separated by a gap 9 and co-operates with a rotatable cylindrical baffle 12 including an aperture 13, so that as the baffle rotates the electron beam from the cathode 5 effectively rotates around the weld line 4 between two rods 1. The cathode is concave to focus the beam on the weld and operates in an atmosphere of argon at a pressure of 0À1 torr. In another arrangement, Fig. 2 (not shown), a rod-like cathode is surrounded by a cylindrical anode closed by an apertured end member; a diaphragm with a small aperture is movable in its own plane between the anode and the work, so that in effect a parallel electron beam may be scanned in a desired pattern over the work.

Abstract: 1,256,952. Casing tube with concreted prestressing members. METALLSCHLAUCHFABRIK PFORZHEIM. 7 Feb., 1969 [24 Feb., 1968], No. 6645/69. Heading F2P. A plastics casing tube which accommodates in concrete therein one, or more, pre-stressed members, not shown, is of helically corrugated form, a continuous helical metal wire, or strip, 12 being fully embedded in the valley parts of the corrugation such that, when the stressing members are stressed, they abrade the valley parts of the tube and bear upon the wire, or strip 12. The tube is made of synthetic thermoplastics and the wire 12 is made of steel. In a modification, Fig. 2, not shown, a shallower corrugation (21) without a wire or strip alternates with a main corrugation which accommodates the wire (22). A casing, which is more nearly cylindrical, Fig. 3, not shown, has the crests of its corrugation flattened. The casing tube 41, Fig. 4, is formed of a helically wound strip of thermoplastic material which is joined by welding its overlapping edges. The profiled strip, Fig. 5, not shown, has positively interlocked edges (53). The wire or strip may be of slightly undulating form or, have thickened portions at regular intervals; alternatively, it may be of strip form of arcuate cross-section and having, on the side which faces the tube axis, axially-spaced bulges. The prestressing members have the abraded plastics material deposited on them to act as a lubricant, while being stressed.

Filed: 1971-10-07
Abstract: 1343690 Automatic control of position ROCKWELL INTERNATIONAL CORP 7 Oct 1971 46804/71 Heading G3R [Also in Division G1] In a system for electrostatically supporting an electrically conductive body, e.g. a gyroscope rotor 11, Fig.4, between at least two pairs of electrodes, the electrodes in each pair are energized from respective amplifiers 51, 53 whose gains are modified in opposite senses according to the output of a circuit which detects any difference in potential between the electrodes so as to maintain the body centrally between the electrodes. Each amplifier of a pair has the same square wave input from a "reference" generator 70 and their gains are varied by the selection of input impedances Ri, which is effected by gauged electronic switches S1, S2 so arranged that the gains of one amplifier is increased when the other is decreased. S1, S2 are normally in position X1 giving equal gains on each amplifier, but during each cycle of the "ref - erence" signal they are temporarily switched by a device 55 to X 0  and X 2  respectively for a time dependent upon the potential difference between the electrodes, measured by an amplifier 56. The switching signal is derived by a "compensator" circuit, Fig. 5, in which the output Vd of 56 is sampled once per cycle by a pulse from generator 70 and converted into digital form. The value Vd is dependent upon the displacement of the body 11 but also upon the position of the switches and their time of operation relative to the sampling instant. However, since this latter term is known it can be eliminated by the circuit shown comprising devices 32, 35 and delay 33. Their function is described in mathematical terms, as also is the calculation for the required duration of the switching signal, produced by pulse width modulator 34. The calculation also expresses the acceleration required to effect correction of the displacement. The complete system comprises four channels like the one shown; a single "reference" generator supplies them all, with 180 degrees phase displacement to two pairs. Each amplifier has a current feedback loop, and the current to one pair of electrodes is returned via one of the pairs with the 180 degrees phase displacement.
